And per their usual bait-and-switch tactics, the co-stars-turned-lovebirds came into the venue around 11 p.m.(separately, of course), but you can’t fool us, Robsten!

“Rob came in and sat down alone for about five minutes,” the onlooker told Celebuzz. “And then Kristen came in with a security guard and sat down next to Rob.”
